To all whom it may concern.-

Be it known that I, CHER POMPEE DE BON- 'DINI, of Constantinople, Turkey, have invented a new and useful Improvement in Ovens, of which the following specification is a full description.

This invention has for its object to utilize the great quantity of heat usually lost in gas works for the manufacture of illuminatinggas; and it consists, first, in heating with the hot waste gasesfisuch as the'products of combustion from the retort-furnacesovens for baking bread, and other like industrial apparatus for baking, drying, and similar purposes involving the use of heat.

It further comprises a special construction of ovcn-to wit, an oven with fiues surrounding the baking or receiving chamber, or a sea vertical section on line y y, Fig. 2. The secsuitable construction, are placed. In the said' wall Ais formed a conduit, B, which receives the products of combustion and other hot gases from the gas-works. v

E is a chimney or uptake, which receives the said gases after they have heated the ovens. The baking or receiving chambers O (of which two are shown, but of which a considerably larger number would ordinarily be employed) have flues c c in the top and bottom, between the walls a a and b b, respectively. These flues receive the hot gases from the conduit B through the opening D and deliver them into the uptake E. As shown, there are two ovens on opposite sides of the common chimney or uptake E, and receiving the gases through inlets D in the wall between them.

Obstructions are shown in the fiues, so as to cause. the gases to pursue a tortuous course.

There may be'several tiers of ovens, if desired, the upper tiers receiving the gases from the lower ones, or being supplied by separate conduits or separate connections with a common conduit. The arrows indicate the direction of the gases. Instead of placing theovens in the position indicated, they could be placed above the retort-furnaces, with an independsource of heat for the ovens at all times with,

out expense forfuel or for attendance on the fires.

I claim- 1. A baking oven or similar apparatus heated by the waste heat from gas-works or other works wherein a high degree of heat is continuously produced, the said oven or apparatus comprising a series of horizontal closed receiving-chambers surrounded with heating -flues, and being combined with a conduit for conveying the hot gases from the retort-furnaces and to said flues, and a chimneyor uptake for carrying off the said gases after circulating through the fines, substantially as de scribed. a

2. The series of horizontal chambers and their surrounding fiues, in combination with the horizontal conduit transverse to the length of said chambers for delivering the hot waste gases into said fines, and one or more chim neys or uptakes for carrying off the same after circulating around the receiving-chambers, substantially as described.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
